Description: Following careful evaluation of the aerial photography, and in some cases creation of a "first draft" habitat map through the process outlined above, selected sites were visited in the field for typological validation. This validation included: (1) areas in the aerial photography and mosaic with confusing or difficult to interpret signatures, (2) transects across many representative habitat types occurring in different depths and water conditions, (3) a survey of the Zones, and (4) confirmation of preliminary habitat delineations if a first draft was produced.
Individual sites were visually evaluated by snorkeling and free diving or directly from the boat in shallow, clear water. Habitat transitions were evaluated by swimming transects across habitat types to further guide placement of polygon boundaries. Habitat type(s), zone, approximate depth, position (GPS), image number, and other descriptive information were recorded at each site.
